Precompute Fugazetteer's build-time-only Shiny inputs — build_shiny

Builds and saves the handful of data/*.rda objects that exist purely so inst/shiny/Fugazetteer/app.R doesn't have to redo, on every app start, joins/aggregations that never touch the app's three live Google Sheets reads (fls_venue_geocoding, quizdata, linktracksindexdata). These are Shiny-presentation-only cached views, not part of Repeatr's canonical data model and not exported to fugazibase - see vignette("Data-Provenance") and the Provenance section on each object's own help page (e.g. ?shiny_shows_data_base). Mirrors the exact joins app.R used to run inline; if app.R's sheet-independent preprocessing ever changes, update both together.

Usage

build_shiny_precompute(output_dir = NULL)

Arguments

output_dir: where to save the rebuilt data/*.rda objects. If omitted, defaults to data/ under the current working directory.

Value

Invisibly, NULL. The real effect is writing the shiny_*.rda files.

Examples

if (FALSE) { # \dontrun{
build_shiny_precompute()
} # }
